INVENTOR M ATTORN EY Patented Apr. 28, 1931 PATENT OFFICE UNITED STATES ALBER'I. S. ALLEN, OF YONKERS, NEW YORK, ASSIGNOR TO DU PONT CELLOPHAN E COM- PANY, INC., 015 NEW YORK, N. Y.,

A CORPORATION or DELAWARE DECORATIVE MATERIAL AND ME'rnon or MAKING s um Application filed April 22,

This invention relates to decorative materials and to the method of preparing the same. Specifically it relates to a decorative wall paper and the process of making it.

In the manufacture of transparent sheets or films of regenerated cellulose there is a substantial amount of waste occasioned by trimming and cutting to size of the sheets or films in addition to that resulting from imperfect products. Prior to this invention such waste materials had no utility and were burned.

I have found that, if this waste material is comminuted and/or disintegrated, it does not lose its luster and scintillating effects but, on the contrary, retains them and, when the particles thereof are employed in the production of designs or patterns, extremely decorative materials including wall paper,

ornamental fabrics, lamp shades and similar materials are obtained.

It is therefore an object of this invention to employ scintillating particles of regenerated cellulose in the production of decorative materials.

Another object of this invention is to provide a decorative material comprising a base having scintillating particles of regenerated cellulose anchored thereto, said particles preferably forming a design or pattern.

Other objects will appear from the following descri tion, appended claims and accompanying rawings forming a part of this specification and in which:

Figure 1 is a top plan view of a piece of decorative material constituting this invention.

Figure 2 is a sectional view taken on lines 2-2 of Figure 1.

Figure 3 is a top plan view of a piece of wall paper having any suitable pattern.

Figure 4 is a sectional view on lines 44 of Fi ure 3.

ccording to this invention, regenerated cellulose, and particularly the waste material resulting from the manufacture of transparent sheets or films of regenerated cellulose, is disintegrated and/or comminuted until .the particles thereof are of any desired degree of fineness. These particles are then regenerated cellulose.

1930. Serial No. 446,416.

used as more clearly explained hereafter in the production of the decorative material.

For convenience and brevity, the invention will be described in connection with the production of wall paper. It is, of course, to be understood that the invention is. not restricted thereto, since it is equally applicable and-successful in the production of divers ornamental products including lamp shades, costume fabrics and analogous materials.

Referring now to one mode of manufacturing wall paper, the paper serving as the base thereof, with or without any suitable surface coating which may serve as a background for the pattern is provided with the desired pattern in any suitable manner, as, for instance, by painting, stenciling or printing an adhesive material or composition thereon. Before the adhesive has set and while it is still wet, the particles of regenerated cellulose are applied to the base in any convenient manner, as by sprayin or dusting. In practice, it has been foun that best results are obtained when the material is applied, and preferably in excess, over the entire surface of the base. The particles adhere to those portions of the base which have been coated with the adhesive and upon drying are securely anchored thereto. The excess is then removed in any well-known manner.

As the securing and anchoring medium, I may use any adhesive material. Satisfactory results have been secured by employing common water-soluble agglutinants including an aqueous mixture of gum arabic and glycerin or any of the varnish type of adhesives. As a matter of preference, I employ adhesives which are not susceptible to moisture, so that even in damp or wet weather the particles will not become matted or loosened.

It is obvious that multi-colored materials may be produced by employing colored or a mixture of variously colored particles of If desired, the pattern may be subsequentl treated as by metallizing or embossing wit out departing from the principles of this invention.

An attractive material may also be obtained by making the pattern in a plurality of colors. One mode of procedure for accomplishing this comprises forming a colored design as reviously described and mentioned. Ot er areas of the base of this ma- 'Figu terial are then similarly treated, whereby another difierently colored design is secured. These steps maybe repeated as many times as necessary to produce the required number of colored areas.

If desired, the entire surface of the base may be coated with scintillating particles of regenerated cellulose.

The products resulting from the hereinbefore described method are extremely ornamental and decorative. As illustrated in res 1-4 inclusive, each material comprises a base material having a plain, colored or multi-colored coating or pattern of scintillating efiects and formed of particles of regenerated cellulose firmly anchored thereto.

11 addition to the products resulting therefrom, the present invention presents an outlet and economic use for a waste product which previously possessed no utility and was a total loss.

Since it is obvious that various changes may be made in the specific details above set forth, this invention is not restricted thereto except as set forth in the appended claims.

Iclaim:

1. A decorative and ornamental material comprising a base having a coatin thereon formed of scintillating particles regenerated cellulose.

2. A decorative and ornamental material comprising a base having predetermined areas coated with scintillating particles of regenerated cellulose. 3. A decorative and ornamental material comprising a base having scintillating particles of regenerated cellulose anchored to predetermined areas thereof.

4. A wall paper having a pattern formed of scintillating particles of regenerated cellulose.

In testimony whereof, I have afiixed my signature to this specification.
